如何从泛型实例中获取目标类名？

import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;

public class GenericClass<T> {
    private Class<T> targetClass;

    public GenericClass() {
        Type superClass = getClass().getGenericSuperclass();
        if (superClass instanceof ParameterizedType) {
            ParameterizedType parameterizedType = (ParameterizedType) superClass;
            Type[] typeArguments = parameterizedType.getActualTypeArguments();
            if (typeArguments.length > 0) {
                targetClass = (Class<T>) typeArguments[0];
            }
        }
    }

    public Class<T> getTargetClass() {
        return targetClass;
    }
}

// 使用示例
public class Main {
    public static void main(String[] args) {
        GenericClass<String> genericClass = new GenericClass<>();
        Class<String> targetClass = genericClass.getTargetClass();
        System.out.println(targetClass.getName()); // 输出 "java.lang.String"
    }
}
